AUTOMOBILE.

Application filed February 26, 1920. Serial No. 361,460.

To all whom it may concern:

Be it known that LRODOLPHE STAHL, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Automobiles, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to automobiles and an object of my improvements is to combine an internal combustion engine with the automobile to which it is designed to furnish power so as to get a better distribution of weight with reference to th center line of thevehicle, a better circulation of the cool- 'ing water, together with a lowering of the center of gravity of the mass, to get an improved accessibility of the parts, and avoid in part the vibration caused by the engine, and without additional cost of construction.

I secure this object by the arrangement illustrated in th accompanying drawing, in which- Figure 1 is an end-view partly in section of an engine and so much of the automobile upon wh1ch it is located as to show the relative arrangement and combination of the two.

Fig. 2 is a side view of the same, the side piece of the chassis toward the observer'being removed. I

0;, a are the side pieces of the chassis; 0, is the hood or engine housing. 0 lndicates the steering post or shaft; d indicates the cylinders.

There are a plurality of cylinders arranged with their axes in the same plane. Such plane is inclined to the vertical at a convenient angle which I have represented as fifteen degrees. e indicates the exhaust and intake manifold and m is the carbureter. 9 indicates the valves which have the not here shown. d are the spark plugs and d indicates the bolts by which the head is secured upon the cylinder casting. a is the water jacket. 7 is the intake passage for water and g is the outlet passage.

The exhaust and intake manifolds, the in-v take pipe .and carburetor being upon one side of the engine with the valves and actuating parts, tend to displace the center of gravity to that side of the center line of the cylinder. The cylinders are, therefore, turned away from the intake side thereof, so as to bring the center of gravity of the entire mass at or adjacent the center of the vehicle. This also brings the valves 9 to a relatively higher position and it brings the water-jacket, which is approximately rectangular in cross-section, so as to have one corner, that is, the right-hand upper corner, as shown in Fig. 1, highest, and the out-take from the water-jacket is at this corner. The intake f is on the other side of the cylinder casting and at the lowest point of the waterjacket, as shown. By this arrangement the weight of the power plant is better distributed, the syphonic action of the water is improved in that the body of water in the jacket is brought to a somewhat lower position and the rising water is guided b converging surfaces toward the out-ta e 9 The cooling water is brought more directly into the region of the valves and keeps them cooler. The valves are at an angle and these valves and actuating parts are more easily accessible as is also the carburetor and other auxiliary parts located in that vicinity. This also leaves room for the steering post a.

From the other side of the power plant, the bolts 03 are readily accessible when it is desired to remove the head from the cylinder casting. The -reciprocating parts nowact said cylinder being provided with apper-' taining parts upon one side thereof extending beyond the body of the cylinder upon that side so that the center of gravity of the structure as a whole is at the said side of the cylinder, said cylinder being inclined to the vertical away from the side upon which said appertaining parts are located so as to bring the center of gravity at a point symmetrical with the spring sup port, substantially as and for the purpose described.

2. In combination with an automobile frame, a power plant having cylinders in line with each other supported on said frame, a hood enclosing said ower plant, said cylinders being provided with an intake and an exhaust manifold upon one side thereof extending beyond said cylinders upon said side, said cylinders being inclined to the vertical away from the side upon which said manifolds are located, and a steering post located in part within said hood upon the side of said cylinders upon which said intake and exhaust manifolds are located.

3. In combination with an automobile, a power plant having a cylinder provided with a cooling jacket of approximately rectangular form in transverse cross-section with reference to the automobile, said cylinder being inclined to the vertical so as to bring one of the upper corners of the crosssection of said cooling jacket to an elevated position, and an outlet conduit from said water jacket at the corner in said elevated position.

4. In combination. with an automobile, a power plant having a cylinder provided with a cooling jacket of approximately rectangular form in transverse cross-section with reference to the automobile, said cylinder being inclined to the vertical so as to bring one of the upper corners of the crosssection of said cooling jacket to an elevated position and a lower corner to a lower position, an outlet conduit from said water jacket at the corner in said elevated position, and

an inlet passage for water located at the depressed lower corner of said water jacket.

5. In combination with an automobile, a power plant having a cylinder provided with a cooling jacket of approximately rectangular form in transverse cross-section with reference to the automobile, said cylinder being inclined to the vertical so'as to bring one of the upper corners of the cross section of said cooling jacket to an elevated posit-ion, and an outlet conduit from sai water jacket at the corner in said elevated position, and valves located adjacent to said elevated upper corner.

6. In combination with an automobile frame supported upon springs, a power plant having cylinders in line with each other supported on said frame, a hood enclosing said power plant, said cylinders bein provided with an intake and exhaust manifold upon one side thereof extending beyond said cylinders so that the center of gravity of the structure as a whole is at the said side of the cylinders, said cylinders being inclined to the vertical away from the side upon which the said manifolds are located soas to bring the center of gravity of the structure as a whole at a point symmetrical with the spring support, and a steering post located in part wit in said hood u on the side of said cylinders at which sai folds are located.

In testimony whereof, I sign this specification.

mani- RODOLPHE STAHL.
